打开文件对话框

Question

我写了这段代码只选择pdf文件,但它不起作用

OpenFileDialog fd = new OpenFileDialog();
fd.ShowDialog();
fd.Filter = "Pdf files (*.Pdf)|*.Pdf";

Answer 1

您需要Filter 在打开对话框之前设置第一个.

OpenFileDialog fd = new OpenFileDialog();
fd.Filter = "Pdf files (*.Pdf)|*.Pdf"; //this should be before
fd.ShowDialog();
